Abstract
When transducer arrays (i.e., arrays of electrode elements) are used to apply alternating electric fields (e.g., TTFields) to a subject's body, the subject may experience electrosensation. This electrosensation can be ameliorated by (a) increasing the amplitude of the field in a series of steps, and allowing some time to pass for the subject to acclimate to each step before the amplitude is increased to the next-higher value, (b) starting out at a frequency that is higher than the recommended frequency for each indication (e.g., higher than 200 kHz for treating glioblastoma), subsequently decreasing the frequency to the recommended frequency in a series of steps, and allowing some time to pass for the subject to acclimate to each step before the frequency is decreased to the next-lower value, and (c) avoiding (or at least minimizing) situations in which an increase in amplitude and a decrease in frequency occur simultaneously.
